"Coventry Wall" Installation:

A trench of 16" wide and 6"-10" below grade, depending on the overall wall height. One (1) inch of block will be buried for every 8 inches of exposed wall height. At the bottom of the trench, the soil will be compacted to prevent settling. A level 6-inch thick layer of compacted 3/4" modified stone will be used for the footing. The base course will consist of the first row of block installed. Adhesive will be used to hold all wall stone in place. Adhesive will be used to hold the 4" pieces in place. Sixteen (16) inch blocks may need to have 2 pins inserted to secure. A backfill 6-12 inches behind each layer of block will be used consisting of a well drained granular fill (3/4 inch clean stone). Al soils/backfill behind the wall will be compacted. The wall cap blocks will be attached with a 1" overhang using a concrete adhesive to secure.
